BMX bike controls digital DJ software

Am I getting this right? Did these crazy Japanese kids actually map the movements of their BMX bikes to the Traktor software to control music? Looks like it, the product is called Turntable Rider and the description reads as follows:

“The Turntable Rider is an epic bicycle accessory which converts a bicycle into a musical instrument.
The bike wheels, become jog wheels.
The handbrakes, become sound pads.
Mix and scratch at will.”
